Flash nv backup from support area https://www.dc-unlocker.com/firmware-catalog Then do IMEI repair.

[fortunaR]

in stock rom after these operation bootlooping
hang on recovery with chinese letters

[Valdemaras]

If the phone does not boot up into the factory home screen with factory apps after bootloader flash then possibly the memory is faulty sadly.

it does boot
but no matter if on stock rom or factory rom
if flash nv then imei repair still
bootlooping or stuck unto recovery

[Valdemaras]

If boot looping or stuck in recovery then it isn't "booting", a phone must boot into the home screen with factory apps after the board flash.

If writing NV backup does not fix an emergency or No service problem then it is related to something else, sadly we do not have a solution for it.
